1.11.1

- Fixed issue that could cause a callback (or zero-duration tween) not to render correctly the 2nd time if seek() is called on its parent timeline from within that same callback (rare, but possible).

- Fixed issue that could cause text selection to remain disabled on the target element of a Draggable after its disable() method is invoked.
